性地卖出了1千多亿元的美债（见上图）！同时，大家都知道中国一直是个国际贸易顺

来，猫腻就在黄金之中（见下图）：中国政府正在通过香港的渠道在国际黄金市场上大
力收购黄金，为即将到来的美元体系崩溃和国际新的黄金货币挂钩体制做准备了。作为
个人投资人，古风也一直在极力建议大家去投资黄金。如果您有真金白银，就把实货存
到香港的银行里去。因为一旦现行的美元体系崩溃，美国政府就会重新干起罗斯福总统
以前在大萧条时期干过的活：搜缴美国民间的金银，充实国库。大家不可不防啊。

发帖数: 30882 | 2 中国在过去几年中，用美国涌入中国大陆的热钱，通过香港不停的收购海外黄金。至今
已经收购了至少6000吨以上，而美国的联邦黄金储备一共才10000吨！目前中国的黄金
储备究竟是多少，中国人民银行拒绝透露，西方媒体估计至少已经超过了6000吨，超过
了德国的黄金储备。
这就解释了，过去几年中国减持的1635亿美元美国国债的去向。而这些黄金的收购，不
通过香港是不可能完成的。也就是说香港在过去几年中一直在帮助中国买入黄金，打击
美元。如果中国继续把持有的美国国债都抛出去购买黄金，那么除非爆发世界大战，美
元体系崩溃基本上就成了定局。因为美国对华贸易是众所周知的连年大逆差，这就决定

来不买，倒也没啥可怕的，改种别的就是了。给点时间，农民会适应的， 而且美国政
府从中国产品收的税中，也给了农民补贴了，以补偿适应成本。
就大豆贸易，2016年美国产量是4.31 billion bushels（117 million metric tons)，
出口到中国是31.86 million metric tons ， 相当于27%. 从下图看，如果没有中国市
场，也就是回到2012年水平。

2019年，种大豆的农民再傻，也应该知道不能把所有鸡蛋放在一个篮子里了。

发帖数: 29846 | 18 造成2008年金融危机的原因，一言以蔽之，就是很多银行向很多人发放了很多贷款，而
这些人要么没能力还款，要么不愿还款。但这个解释带出了两个关键问题。首先，其本
职工作就是评估信贷风险的私营借贷机构为什么会发放那些贷款？其次，拥有大规模强
制权力的众多金融监管机构为何会允许银行发放了2,800万笔高风险贷款？
答案可追溯至1992年9月12日，这么做的理由很充分。那一天，美国总统候选人比尔·
克林顿(Bill Clinton)在其“把人民放在第一位”的竞选口号中提出，用私人退休基金
“投资”政府重点项目，如保障性住房，从而“产生长期、普遍的经济效益”。一个选
战中如此激烈的主张竟然被如此轻易地忽视，这种事几乎从未发生过，但却在后来导致
了极具破坏性的后果。
克林顿当选后指定劳工部长赖克(Robert Reich)负责从私人养老金投资中获得“社会性
、辅助性和经济性效益”的行动，这是赖克1994年在国会作证时说的。赖克号召养老基
金加入政府的“经济目的投资计划”。美国住房和城市发展部长西斯内罗斯(Henry

以我现在反而觉得可能问题还是出在交流上，或者你和面试官的background不match：
他想展开来说的部分恰恰不是你所长。
另外，我建议不要有任何hidden assumption，比如你自动假定是server side问题，自
动假定有一套完整的“server side latency metrics”。所有的假定，你不妨都问问
。
很多时候，之所以会有hidden assumption，就是因为潜意识里把自己所知不多的领域
给跳过了。但万一那就是考官想详细问一下呢？比如如何设计“server side latency
metrics”？比如html和js如何设计可以为前端提速？ |

发帖数: 34805 | 50 I would set up metrics to cover the frequent API calls for both volume and
latency. I would have the metrics logged to a separate server and displayed
on a timeline chart, and alerts to warn me
if the volume/latency is over certain threshold compared to history. I
would even set up circuit breaker if self recovery is possible. It
should be pretty easy to narrow down which call is causing trouble. there
are open source tools on all these.
The key is to prepare, not react on such accidents. If the... 阅读全帖 |
